Canada is another option. Canada has significant AI research institutes going back decades ( https://en.wikipedia.org/wiki/Mila_(research_institute) ) that have produced much of the foundational research that backs today's AI models.

For Americans and international researchers it's easy to get visas there quickly. It's not far at all for Americans to relocate to or visit. Electricity is cheap and clean. Canada has the most college educated adults per capita. The country's commitment to liberalism, and free markets, is also seeming more steadfast than the US at this point in time.

Canada faces obstacles with its much smaller VC ecosystem, its smaller domestic market, and the threat of US economic aggression. Canada's recent trade deals are likely to help there.

I say this all as an American who is loyal to American values first and foremost. If the US wants to move away from its core values I hope other countries, like Canada or the EU, can carry on as successful examples for the US to eventually return to.

Canada is not as good as Europe when it comes to be out of reach of the US
